# What Is the Formula for the Area of a Circle?

The formula area of a circle is 2 pie is a symbol representing the numerical value 22/7, while r is the radius of the circle. The formula of a circle was first worked out by Archimedes.

The formula for finding the area of a circle is A=(pi)R^2.
R is the radius of the circle.
The formulae for the area of a circle is pi r2. In this formulae, Pi is 3.142 and r represents the radius of the circle. To get the area of a circle, Pi is multiplied by the radius squared.
The area of a circle is the number of square units inside that circle. The area of a circle is obtained by multiplying Pi (?) by the radius squared. (Pi is usually 3.14).
An area is a part of a structure having some specific characteristic or function. The area of a circle = ? r2 (r is the radius of the circle).

 you take the radius which is half of the diameter to the second power then multiply that to pie, which is usually 3.14 but if you look at a calculator their is actually a pie button http://wiki.answers.com/Q/What_is_the_area_formula...
 The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r). 2. http://wiki.answers.com/Q/What_is_the_formula_for_...
